ABStolinear.xlsx: the first sheet is the first program which is correct (i think), the second sheet is a failed attempt to write the second program

Macro To Run SOLVER Across Several Sheets On Linear Program

Nov 18, 2012

Writing a macro to run SOLVER on a linear program. I have twenty tabs, each with a linear program and a solver already set up (constraints, cells to change, and cell to maximize). I would like to run a sub that will solve each tab's LP by running the tab's SOLVER...

If it makes it easier, my cell to maximize is I17, by changing B16:H16, subject to I20:I40 SolverAdd -> SolverOk -> SolverSolve

Absolute Column And Absolute Row Problem

Jan 14, 2009

I have a simple count formula which is suppose to be absolute.
=COUNT($L5:$V5) and works till I add a column via a macro.
Macro adds a new column at column M then inserts data.
My problem is when I check the formula after macro it changes to
=COUNT($M5:$W5) I thought using the $ sign means Don't change?

VBA: How To Get Either Absolute Column Or Absolute Row Only

Oct 22, 2007

how to get either the absolute row or the absolute column of a cell.

Suppose the active cell is H27.
If we use:

ActiveCell.Address
we will get $H$27

How can we get either $H or $27 only assigned to a variable let it be MyVar.

Please keep in mind that converting the $H$27 to a string and then making string manipulations is not accepted, unless of course it's the only way to go.

Also it would be nice if I get answers on how to get the relative address column/row portions only, too. Like H or 27.

Another tip is that using .Column returns a number, not a letter.

Linear Interpolation

Feb 10, 2007

need an excel simple formula or function that returns values of y for given x in a two-dimensional array and works in the following way.actually a combination of linear interpolation and lookup/linear search. as in following example

x y
1 10
2 15
3 20

if x=1.5 then y=12.5 (answer available thru FORECAST but incomplete)
if x=2 then y=15 (answer available thru LOOKUP but incomplete)

so for whatever the x i need/get a valid y thru a single formula/method !
sorry m not good in math,

Multiple Linear Regression In VBA?

Oct 16, 2008

I would like to run a multiple linear regression in vba. I have one dependent and three explanatory variables. I will have to use a macro of some kind, since I need to run too many regressions to do it manually. To simplify things a little bit:

- There will always be exactly three independent variables

- There are no missing values

- The data is allways numerical

I've already got four ranges defined: Yrange, X1range, X2range, X3range. I would like to take these ranges as input parameters for the regression model. The only two parameters I need are Sum Square for Regression (SSR) and the degrees of freedom. I understand that you can use excel's matrix formulas to calculate some of the input parameters, but one doesn't really get around vba. Any (simple) source code allowing me to conduct a regression with three input parameters?

Bi-linear Interpolation VBA Code

Feb 10, 2009

I have 3 equations and have created the relevant chart from them. What I would like to do is put in a value of x & y and get result z. Having done a search through previous threads I found some BiLinear Interpolation code that works using the table in a workbook, but what I'd really like is the Interpolation of the formulae rather than the resulting table and for it to be embedded in VBA.

Forecast Linear Trend Between Min & Max

Jan 4, 2007

I am using the Forecast formula to give me a value from a Linear trend. However I need to limit the resulting value that is displayed within a min and max value. Background: This is to allow me to calculate the amount of bonus someone will earn depending on the Percentages of their target they achieve. The min bonus is 25% when 80% of target is achieved and max bonus is 100% when 125% or greater of target is achieved.
So the Forecast formular works great using the existing values, but i need help limiting the results to between 25% and 100%. I was trying to use a sumif formula to copy the resulting cell but only if the value fell between the 25 and 100%. I've attached the spreadsheet as I think it will highlight what i'm trying to do better than I can explain it.

Calculate A Linear Sliding Scale

Oct 9, 2008

I need a formula to calculate a linear sliding scale from 10%-30% (no higher, no lower). Based on the data in the below chart, if the GROR (let's say this is known and the result resides in cell A1) is less than or equal to 0.0% the payout % is 10.0% and gradually increases as the GROR increases.

The payout % is capped at 30% which is if GROR is 18% or greater. Below are just some examples of how certain thresholds should calculate.

GROR 0.0%5.0% 8.0% 11.0% 14.0% 18.0%+
payout %10.0%10.0%14.6%19.2%23.8%30.0%

The data set I am applying this to has 180 data points and the linear weights should extend back over the last 30 points.

3D Linear Algebra. Translate To Best Fit Plane

Mar 20, 2008

I have several hundred points in cartesian x,y,z coordinates. I used an Excel add-in program to calculate the equation of best fit to the points. The equation is:

z=A*x+B*y+C
where (for this case):
A= 2.29091
B= -1.77338
C= -192.494

My objective is to define the several hundred x,y,z points in cartesian coordinates about a new cartesian coordinate system whose origin is the centroid of the data points and whose z plane (ie z=0) is equal to the best fit plane defined above (when referenced from the original coordinate system).

Using Pro/e (a cad program), I was able to create the new coordinate system using the x, y, and z intercepts from the best fit plane, and then was able to redefine the points about the new coordinate system. After the points were redefined in Pro/e, I was able to export the points back to Excel; however, I would prefer to only use Excel / VBA because I prefer the calculations be transparent for optimal accuracy and validation.

Linear Regression Array - Significance Of R Testing

May 5, 2014

I have set up a linear regression array in Excel and now want to test the significance of my r2 value at a certain level of significance. I've only been able to find tables that give the critical r value, but I want to test it at 99.73% level of confidence and none of them contain that specific value. Is there a way to do this in Excel?

Forecasting Using Historical Seasonally Effected Non-linear Data

Jan 15, 2010

Forecasting using historical seasonally effected data

I organize my thoughts in numbers so it will be easier to understand.

[1] Say I have this data from January 2009 to December 2009:

1-4-7-10-13-14-15-16-18-20-22-25

As you can see, the growth is not linear.

[2] So then, I start with this data point for Janaury 2010.

26-a-b-c-d-f-g-h-i-j-k-l

[3] I now want to forecast that data point for the rest of 2009...using the growth in [1]. SO i guess that's an easy task right? Take the percentage change from Jan 08 and Feb 08...and apply that to the 26...and so on. (am i correct here at least).

[4] But lets say we have a GOAL. So, this become a forecast/plan. In December 2010, i want to grow double the amount of that in December 09. So 25 x 2 = 50. Now, the "known" data is like this:

26-a-b-c-d-f-g-h-i-j-k-50

So how do i do this now?

Excel 2010 :: Finding Values Using Linear Extrapolation?

Mar 26, 2014

I am looking to find out certain values from a current set of data using linear extrapolation in Excel 2010.

I have attached the data i am using below:

Data.png

I need to find out the specific power output and heart rate values, at a set blood lactate value (i.e. When the blood lactate value is exactly 2.0mmol.L-1, what is the given power output and heart rate).

I have tried plotting the data into a line graph with a secondary axis, however because i am unable to change the horizontal axis range for the power output values, i cannot interpret the data in this way.

Estimate Linear Formula From Multiple Coordinate Pairs

Aug 13, 2007

I have 32 pairs of coordinates (X,Y). If I graph them using a scatter chart in Excel, I can see that it looks like they suggest a linear relationship between the points.

Other than printing the chart and trying to draw a "best fit" line manually, is there some sort of way I can get Excel to come up with the "best" linear formula (y=mx+b format)?

Automating Linear And Growth Trend Auto Fill

Jun 16, 2008

I used HTML Maker to show my sheet below. I want to have cells K3:Z3 automatically populated using the same calculations as "Linear Trend" Auto Fill and K4:Z4 using "Growth Trend" Auto Fill without having to do it manually. The data in Row 2 will of course be continually updated with actual scores so the remaining empty month scores would need to be updated again. I am using this to come up with a more accurate prediction method than a simple trend line in Excel graphs.
